Want to know if the reflectance measured in a FDTD simulation at off-normal angle of incidence is specular or diffuse type? Or both? Thank you.March 7, 2022 at 6:49 pmKyleAnsys Employee
FDTD directly solves Maxwell's equations, so it will include both specular and diffuse reflection. An exception would be when you're using a TFSF source with a scattering object on a substrate, in which case the specular reflection from the substrate would be removed.
